A homeowner in Chelmsford contacted us after leaks were traced to deteriorated ridge caps and failing roof valleys — two of the most weather-exposed components on any Massachusetts roofing system. We removed and replaced 130 linear feet of ridge caps with Owens Corning Ridge Caps in Onyx Black, then removed shingles across all 81 linear feet of valley areas, installed High Temp Ice and Water Shield as the base membrane, and completed the system with new black metal valleys throughout. Both upgrades were completed in a single mobilization for maximum efficiency and minimal disruption. If you're in Chelmsford or nearby towns north of Boston dealing with ridge or valley leaks, schedule your free inspection today.
